support the argument that hominins may have been subject to selection promoting both consideration of others and sensitivity to local norms of fairness.
While other experiments have established that chimpanzees do show impressive proficiency in social learning and social cognition,105 those studies that directly compare species nonetheless consistently reveal strong differences between humans and other apes.106 The hypothesis that social intelligence, in particular, blossomed among our hominin ancestors is now widely accepted.
communication systems cannot be arrayed on a continuum of similar forms, with human language at one end of the spectrum, closely aligned to some highly complex animal protolanguage, and passing through less and less sophisticated animal communication systems to end up with, say, simple olfactory messages at the other end. Rather, language appears qualitatively different.
For instance, Culum Brown, an Australian biologist who spent a period as a postdoctoral researcher in my laboratory at Cambridge, discovered that showing young salmon “video nasties” of other salmon being eaten by a pike was sufficient to train them to avoid large predators, a crucial life skill for a young fish. He was also able to “teach” salmon fry to consume appropriate novel foods by watching more experienced fish.113 Subsequently, some Queensland hatcheries exploited our social learning protocols as part of their efforts to enhance the returns of salmon and other fish introduced...
